Description

[Detailed Description of the Invention] The present invention relates to a container with a makeup brush for eyeliner and the like.

A cosmetic tool for liquid cosmetics has been provided which has a makeup brush attached to one end and has a pencil-like shape as a whole for ease of use and portability. However, conventional products have a complicated and sophisticated structure, such as using a cartridge type cosmetic liquid storage section, and require more than 10 parts.

The object of the present invention is to provide a container with a cosmetic brush that has a particularly simple structure, requires only a small number of parts, and can be refilled with cosmetic liquid.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 and 2 are a rotary operation cylinder and a main cylinder that are rotationally driven relative to each other. The rotary operation cylinder 1 has an upper outer surface of a peripheral wall 3 cut, a groove 4 formed around the cut outer surface, and a tall prismatic column 5 extending upward from the center of the bottom wall. The main cylinder 2 is an elongated one with a stepped upper half, and a protrusion 6 provided around the inner periphery of the lower end is fitted into the groove 4 to rotatably fit into the rotary operation cylinder 1. , and are provided so as to extend upward from the peripheral wall 3.

A screw tube 7 is fitted into the prism 5, which is movable up and down with respect to the prism 5, but which rotates with the left and right rotation of the rotary operation tube 1. This can be done by making the fitting hole of the screw tube 7 into a square hole and loosely fitting it into the square column 5.
The upper end of this screw tube 7 is closed by a member projecting upward, and an engaging protrusion 8 is provided on the outer periphery of this member.

A screw ring 9 having a screw groove formed on the inner circumferential surface is integrally provided in the large diameter portion of the main cylinder 2 immediately below the intermediate step portion,
The threads on the outer surface of the threaded cylinder 7 are threaded into the threaded grooves of the threaded ring 9. Further, a piston 10 is slidably inserted into a small diameter portion above an intermediate stage portion of the main cylinder 2, and the portion above the piston 10 is formed as a liquid storage chamber for storing a cosmetic liquid 11. The piston 10 is fixed to the upper part of the threaded cylinder 7 by engaging the engagement protrusion 8 in a groove on the inner circumference of the vertical ring 12.
Each of the above parts constitutes a liquid extrusion part that pushes out the cosmetic liquid 11 in the liquid storage chamber upward.

Reference numeral 13 denotes a tapered nozzle-shaped pouring spout, with a small-diameter opening at the tip to which a makeup brush 14 is attached, and a base with a double cylinder, with a protrusion 15 on the inner circumference of the outer cylinder connected to the diameter-reducing opening at the upper end of the main cylinder 2. It is fitted in a groove on the outer periphery in a liquid-tight manner. 16 is a cap.

When using this configuration, remove the cap 16, grasp the main cylinder 2 with one hand, pinch the rotary operation cylinder 1 with the fingers of the other hand, and rotate it clockwise relative to the main cylinder 2. let Then, the screw tube 7 rotates in the same direction as the rotary operation tube 1;
is simultaneously screwed into the screw ring 9 and is movable up and down relative to the prism 5, so that it moves upward due to the screwing, thereby pushing the piston 10 upward.
Due to this upward movement of the piston 10, the cosmetic liquid 11 is pushed out to the spout portion 13 and oozes into the makeup brush 14, so that the tip of the makeup brush 14 contains a sufficient amount of the cosmetic liquid 11.

As described above, in the present invention, the spout part 13 is made removable, and the vertical ring 12 is provided on the lower surface of the piston 10, and the piston 10 is fixed to the upper end of the screw tube 7 via the vertical ring 12. By rotating in the opposite direction, the piston 10 can be returned to its original position, thereby making it possible to easily replenish the cosmetic liquid 11. There is no need to use a cartridge type cosmetic liquid storage section, and the configuration is Can be simplified. That is, the number of parts can be reduced to six parts by omitting the makeup brush 7, which can be reduced by approximately half compared to conventional products, and the cost can be reduced significantly.
